Green Synthesis of CuO -Ni Foam Heterojunction nanoparticles via Dip-Coating forEfficient Visible Light Photocatalytic Oxidation of Benzyl Alcohol to Benzaldehyde

The CuO-Ni foam heterojunction nanoparticles was prepared using a sustainable Green synthesisapproach known as Dip-coating. This innovative method enabled the in-situ photocatalytic oxidation of benzylalcohol (BA) to aldehydes when exposed to visible light. The CuO catalyst supported on a nickel foam bed playeda crucial role in catalyzing the conversion of benzyl alcohol to benzaldehyde. Subsequently, the benzaldehydeunderwent condensation with o-phenylenediamine, yielding a diverse array of ۲-substituted benzimidazoles.These compounds serve as vital intermediates in pharmaceutical synthesis. The photocatalytic reaction occurredunder green laser light with a wavelength of ۵۳۵ nm. The reaction was conducted in water at ۴۰°C for a durationof ۶۰ minutes, resulting in an impressive efficiency of ۸۹%. The nanocomposite was meticulously characterizedusing a range of analytical techniques including FT-IR, XRD, FESEM, and Matt Schottky analysis
